Direct Current was the "electromedicine" of the early 1900s and was very successful. almost all doctors used DC battery powered devices to treat their patients and electromedicine was taught in the medical schools. Now you can apply DC to any bacterial infection using the combo Microbe Electrifier / DC Electrifier that Bioelectric sells.
